a method of preventing a striker, said method comprising: the tool shank 2 is sleeved with a protective sleeve 3, a colored coating with a color different from that of the body of the protective sleeve 3 is sprayed on the surface of the protective sleeve 3, a color sensor 4 is mounted on the spindle 1, the color sensor 4 is used for acquiring image information of the protective sleeve 3, and the color sensor 4 is in signal connection with a PLC (programmable logic controller); the color sensor 4 is used for identifying the color of the coating of the protective sleeve 3, the workpiece 5 and the cutter handle 2 are touched, the color of the coating outside the protective sleeve 3 is removed, and the color sensor 4 shoots the color change to transmit an alarm signal to the PLC.
In the structure, be used for gathering protective sheath 3's image information, its image information takes place the difference colour difference pattern of mar for coloured coating, colour sensor 4 installs back on main shaft 1, calibration colour sensor 4 aims at protective sheath 3's surface spraying and has the coating, only need normal clamping milling cutter 6, if the clamping mistake of makeing mistakes, when the work piece bumps with the cutter, the mar appears in the coating of plastics protective sheath outside, or the picture layer colour fades, the common white transparent plastics that use, consequently, the handle of a knife is dark brown for ironmaking metal material, the selection coating is any one of three primary colors, for example: in order to reduce chromatic aberration, a single color layer is selected and is obviously different from other visible colors on the protective sleeve 3, for example, magenta, yellow and cyan are selected, any one of three coatings is coated on the surface of the protective sleeve 3 to enhance color contrast, when a coating on the protective sleeve 3 sleeved on the milling cutter 6 collides with a workpiece, the surface of the coating is scratched, the color sensor 4 shoots the change of the color of the scratch of the coating and transmits an alarm signal to the PLC, the PLC controls the driving device to stop working, and then the milling cutter 6 stops working, so that the workpiece is not influenced; after the installation is finished, the dependence on personnel is reduced, and the efficiency and the stability of clamping the cutter in the later period can be improved; the rejection rate of the workpiece is reduced, the company cost is reduced, the protective sleeve is made of plastic, the plastic material is beneficial to reducing extra load, meanwhile, the plastic protective sleeve is simple in machining process and low in cost, the protective sleeve is annular, the protective sleeve 3 is conveniently sleeved on the body surface of the milling cutter 6, finally, the primary color of the sprayed coating is any one of three primary colors, the thickness of the sprayed coating is further limited to be 0.5-1 mm, the purpose is that in order to ensure that the milling cutter 6 is long enough in reaction time after collision, the sprayed coating plays a role in isolation, and the milling cutter 6 is relieved from being corroded.
When the color sensor 4 is installed, a specific model can adopt a CFO100 color sensor, and a projection area of a lens of the color sensor 4 is required to cover an area coated with a coating, as shown in fig. 2, there are two methods for identifying chromatic aberration of the coating color by the color sensor 4, and the first method includes the following steps:
the color sensor 4 is used for acquiring the image information of the protective sleeve 3 and comprises the following steps:
s1: the color sensor 4 acquires a first image at a first point in time;
s2: the color sensor 4 acquires a second image at a second time point after the first time point;
